Agent FS gives AI agents a structured filesystem with built-in semantic search, versioning, and identity management. It runs as a CLI and an HTTP server with integrated MCP support — so any AI coding assistant can use it as a long-term memory and file store.

agent-fs was built to power the shared filesystem in agent-swarm — a multi-agent coordination framework. While it was designed for swarm agents to share files, search content, and collaborate, it works as a standalone filesystem for any AI agent.

Key Features

• Semantic search — Index and search files using vector embeddings (OpenAI, Google GenAI, or local llama.cpp)
• Structured storage — SQLite-backed file operations with metadata and versioning
• S3-compatible sync — Sync agent workspaces to any S3-compatible object store
• Identity management — Persistent agent identity files that evolve over time
• MCP integration — Expose filesystem operations as MCP tools for Claude Code, Codex, and other assistants
• HTTP API — RESTful server powered by Hono for programmatic access
• CLI — Single binary (agent-fs) for local use and scripting

Quick Start

Architecture

Agent FS is a Bun monorepo with four packages:

| Package | Description | |---------|-------------| | @desplega.ai/agent-fs-core | Core library — storage engine, semantic search, identity, S3 sync | | @desplega.ai/agent-fs | CLI binary (agent-fs) | | @desplega.ai/agent-fs-mcp | MCP stdio proxy + tool registration for the HTTP server | | @desplega.ai/agent-fs-server | HTTP server — RESTful API powered by Hono |

Documentation

• MCP Setup Guide — Connect agent-fs to Claude Code, Cursor, or any MCP client
• Deployment Guide — Local, remote S3, team, and multi-agent deployments
• API Reference — HTTP API and OpenAPI spec

Development

bun install          # Install dependencies
bun run typecheck    # Type checking
bun run test         # Run tests
bun run build        # Bundle CLI for npm

See CONTRIBUTING.md for the full development guide.

Releasing

1. Update version in root package.json
2. Commit the version bump
3. Run ./scripts/release.sh

This creates a git tag and pushes it, triggering the release workflow which publishes to npm and creates a GitHub Release.

Deploy to Fly.io

Deploy a persistent agent-fs instance to Fly.io with Tigris S3 storage:

git clone https://github.com/desplega-ai/agent-fs && cd agent-fs
bun run scripts/fly-deploy.ts

See DEPLOYMENT.md for Docker, BYOK storage, and manual setup options.

Live Viewer

live.agent-fs.dev — A stateless browser UI (local storage only) for inspecting any agent-fs deployment. Point it at your server URL to browse files and search content — nothing is stored server-side.
